A communication device is made with a metallic frame having an interior mounting surface for receiving one or more functional components. The metallic frame includes a first frame member having a first portion extending uninterrupted across one lateral side of the metallic frame. The first portion provides structural support to the communication device. A T-shaped slot antenna is formed in a second portion of the first frame member adjacent to the first portion. The T-shaped slot antenna has first and second arms separated at a gap and partially encompassing a slot. The second portion of the first frame member enables radio frequency communication by at least one of the functional components via the T-shaped slot antenna of the communication device.

A wireless power receiving system includes two or more electrically small antenna arms and a common antenna ground. The two or more electrically small antenna arms are connected to the same common antenna ground and are close enough to one another to be strongly coupled. In some embodiments, the two or more electrically small antenna arms are tuned to the same functional frequency so that they load one another to create self-resonance. The wireless power receiving system receives the transmitted wireless power wave emitting from a wireless power transmitter without added lossy matching components.

The present disclosure provides an ultra-wideband antenna for a reversible electronic device in a narrow space including: an upper half and a lower half; a hinge connected with the upper half and the lower half; a first RF signal source, loaded on the hinge; an electrical connection structure, placed on one side of the first RF signal source and electrically connected with the upper half and the lower half; a gapped groove, extending inwardly to the electrical connection structure along the outer side of the upper half and the outer side of the lower half; the hinge is spanned on the gapped groove; the hinge excites the gapped groove to form a first ultra-wideband antenna. While realizing the ultra-wideband antennas, it can also integrate with other multiple antennas, and their isolations are better than −10 dB, which basically meets the antenna performance requirements.
